(
Stop!
ƒ Only connect the controller to the permitted mains voltage (
^ Technical
data). A higher mains voltage destroys the controller!
ƒ Some controllers may only be actuated with a mains choke or mains filter.
This requirement can differ with regard to operation at rated power and
operation at an increased rated power.
ƒ The leakage current to earth (PE) is > 3.5 mA. In accordance with
EN 61800−5−1 a fixed installation is required. The PE conductor has to be
designed double.

Supply conditions
Range Description
Fuses l Utilisation category: only gG/gL or gRL
Cables Laying systems B2 and C: Use of PVC−insulated copper cables, conductor temperature < 70 °C,
ambient temperature < 40 °C, no bundling of the cables or cores, three loaded cores. The data are
recommendations. Other dimensionings/laying systems are possible (e.g. in accordance with
VDE 0298−4).
RCCB l Controllers can cause a DC current in the PE conductor. If a residual current device (RCD) or a
fault current monitoring unit (RCM) is used for protection in the case of direct or indirect
contact, only one RCD/RCM of the following type can be used on the current supply side:
– Type B (universal−current sensitive) for connection to a three−phase system
– Type A (pulse−current sensitive) or type B (universal−current sensitive) for connection to a
1−phase system
Alternatively another protective measure can be used, like for instance isolation from the
environment by means of double or reinforced insulation, or isolation from the supply system
by using a transformer.
l Earth−leakage circuit breakers must only be installed between mains supply and controller.
Observe all national and regional regulations!
